关于resetlogs与incarnation理解.docVIP

关于alter database open resetlogs及incarnation的理解 不完全恢复只能做一次吗？ 采用rman的默认设置，对数据库进行了backup database备份。进行了一些操作后，然后直接关闭启动到mount状态 RMAN run{ 2 set until time to_date(2010-10-16 23:14:42,yyyy-mm-dd hh24:mi:ss); 3 restore database; 4 recover database; 5 } executing command: SET until clause Starting restore at 17-OCT-10 allocated channel: ORA_DISK_1 channel ORA_DISK_1: sid=156 devtype=DISK channel ORA_DISK_1: starting datafile backupset restore channel ORA_DISK_1: specifying datafile(s) to restore from backup set restoring datafile 00001 to /oracle/oradata/denver/system01.dbf restoring datafile 00002 to /oracle/oradata/denver/undotbs01.dbf restoring datafile 00003 to /oracle/oradata/denver/sysaux01.dbf restoring datafile 00004 to /oracle/oradata/denver/users01.dbf restoring datafile 00005 to /oracle/oradata/denver/example01.dbf channel ORA_DISK_1: reading from backup piece /oracle/flash_recovery_area/DENVER/backupset/2010_10_16/o1_mf_nnndf_TA230845_6cmhzz8t_.bkp channel ORA_DISK_1: restored backup piece 1 piece handle=/oracle/flash_recovery_area/DENVER/backupset/2010_10_16/o1_mf_nnndf_TA230845_6cmhzz8t_.bkp tag=TA230845 channel ORA_DISK_1: restore complete, elapsed time: 00:01:26 Finished restore at 17-OCT-10 Starting recover at 17-OCT-10 using channel ORA_DISK_1 starting media recovery archive log thread 1 sequence 10 is already on disk as file /oracle/archivelog/1_10_732510268.dbf archive log filename=/oracle/archivelog/1_10_732510268.dbf thread=1 sequence=10 media recovery complete, elapsed time: 00:00:01 Finished recover at 17-OCT-10 RMAN alter database open resetlogs; database opened 发现刚才恢复的时间23:14:42有点早，于是想改为恢复时间点为23:17:26，于是再次关闭数据库，mount状态下，但是出错了 RMAN run { 2 set until time to_date(2010-10-16 23:17:26,yyyy-mm-dd hh24:mi:ss); 3 restore database; 4 recover database; 5 } executing command: SET until clause using target database control file instead of recovery catalog RMAN-00571: =========================================================== RM
